The Powermatic PM1000-TKLPRK: .079″ Low Profile RK in Powermatic WW, Table Saw Accessories
The riving knife rises and lowers with the blade, thus maintaining very small clearance between itself and the blade. This helps prevent rotational kickback, by keeping the kerf from binding when it has cleared the blade. The low profile knife sits just below the apex of the blade, and doesn’t require removal when doing non-through cuts. And the thin kerf feature allows the use of thinner blades to reduce kerf waste.
